BBICK-MASONS JOINT BAKER AND SMOOTHER.

Specification of Letters Patent.

Patented J an. 28, 1919.

Application filed May 6, 1918. Serial No. 232,929.

To all whom it may concern: I

Be it known that I, FRED H. AoKERsoN, a citizen of the United States,and a resident of Wichita, in the county of Sedgwick and State ofKansas, have invented certain new and useful Improvements inBrick-Masons Joint Bakers and Smoothers, of which the following is adescription, referring to the accompanying drawings, which form a partof this specification.

In the invention, an instrument or holder is adapted to receiveinterchangeable tools, each tool being suited for raking out the mortarin the joints of a brick wall to a desired depth and at the same timesmoothing the face of the mortar joint to conform to a finish or designsuch as might be specified.

In the drawings, Figure 1 represents a top View of the holder and alliedtool combined therewith. Fig. 2 is a side view of Fig. 1. Fig. 3 is anend view of Fig. 1 looking in the direction of the arrow. Fig. 4 showsthe composite tool in operative position upon a brick wall. Fig. 5 is asectional view of a brick wall showing some of the various groovings ofthe mortar joints; opposite each of said mortar joints is shown thetool, in front and side views, adapted for finishing said joint.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings. Referring to the drawings, Fig.

1 shows the holder comprising a handle 10 and a forked bar 11 integrallyconnected at 12 the base of said forked bar. The outer ends 13, 13 ofthe bar 11 are connected by a cross bar 14. This cross bar 14 has a hole15 drilled through same from top to bottom thereof and located midwaybetween the ends 13, 13 of the forked bar. The under side of the hole 15is enlarged at 16 to provide a recess to receive a nut for the purposesfurther described. It will be further observed that the forked bar 11 isbent at 17, 17 intermediate its ends 13, 13 and its connection 12 withthe handle 10 whereby the outer portions 13, 17-13, 17 form runners 18,18 depressed to a plane substantially parallel with the plane of thehandle 10. By reference to Fig. 4 it will be seen that these runners 18,18 are adapted to stagger the mortar joint and contact with the twobricks 20, 20 so that the hole 15 points directly toward the mortarjoint 19. The handle 10 as will be seen is away from the brick surface aproper distance so that the mason can grasp same and draw the compositetool along the face of the wall in the position illustrated.

By means of the various tools illustrated in the drawings any desiredgrooving or finish may be obtained for the mortar joint. The toolconsists, first, of a finishing portion 21 of the desired shape toproduce the specified joint; for instance, in the series of tools, 21 isconvex to produce the concave joint 19*. Tool 21 shown in front and sideviews produces the V-shaped mortar joint 19". Tool 21 shown in front andside views produces the mortar joint 19. Tool 21 produces the convexjoint 19*. The joints 19, 19, 19 and 19 are surface joints, while thejoint 19 produced by the tool 21 is a recessed joint of any desireddepth. All the above described tools are rounded along their operativeface edge as seen at 23 and in the various side views of the tools at23", 23, 23 and 23*, this permits of a smoothing effect to be given tothe joint as the tool moves over same. The tool seen at 21, in front andside views, will produce the recessed joint 19 but itwill be a roughraked joint since the surface of the tool 21 is provided with cornersadapted to rough up the mortar in contradistinction to the smoothing outof the joint obtained by the curving surface 23 of 21.

Each tool of the series 21 is provided with a threaded shank 24, and anut 25 is adapted to be screwed thereon, then the upper portion of theshank 24 is passed upwardly through the hole 15 in the cross bar 14 ofthe holder until the nut 25 engages within the recess 16 provided in theunder side of the cross bar 14. The adjustment which de termines thedepth that the joint will be raked is made by screwing the nut 25 up ordown on the shank 24 and then securing the tool to the cross bar bymeans of the upper thumb nut 26 which is screwed down on the upperportion of the shank 24 to a contact with the upper face of the crossbar 14. This as will be readily understood by reference to Fig. 4 willmove the finishing head 21 of a tool at right angles to the plane ofcontact of the runners 18, 18 and brick 20, 20 to obtain the desireddepth of the grooving such as is illustrated in Fig. 5.

For inside corners and other inaccessible places, a special rake or hook27 is provided at the outer end of the handle 10. This rake 27 Would bepreferably faced at 28 to conform to the shape of the tool 21.

Such modifications may be employed as lie Within the scope oftheappended claim.

Having fully described my invention, What I noW claim as new and desireto secure by Letters Patent is:

In combination in a brick masons joint raker, a holder having a handleintegral With the base of a forked bar, the outer ends of said bar beingbent to form paired runners integrally connected by a crossbar, a holecentrally located in said cross bar at right angles to the plane of thebase of said paired runners; and-a tool having a finishing face ofsuitable configuration for the specified purposes and a threaded shankportion integral With said face portion, a nut adjustably screwedthereon, the upper end of-said shank-being adapted to enter the hole insaid cross bar of the holder from the under side so that said adjustablenut shall contact said cross bar, and a nut adapted to b'e screwed downon said upper shank portion to contact said cross bar and secure saidtool in operative position as specified.
